Multi 10:4 Trader EA

[Wkcfx]

Andy - Slipshod - All
Finally got 2.01a up and running, kicked it off 17th morning just before Asia session. I had a few issues with the DLL because I run a couple of platforms on different brokers and machines and keep all the templates, experts etc. synced by using a symbolic linked master folder which lives on dropbox so problems are to be expected and certainally NOT related to the EA.
It is running on Alpari UK demo OOTB

The good new is it is doing a great job!

Thanks very much!! you guy are smokin..........

Andy.. I don't know I ask to much maybe... but... maybe the best solution will be to implement 10.5 rules (entry rules - more trades higher gains, the same dd)

[fxYogi]

Concerning excessive drawdowns, I suspect that it is caused by trading too many pairs of a certain currency at the same time. For example there are 7 JPY pairs on the list of default currencies. If there is a strong move of the JPY then the EA may enter all- or the majority of the 7 pairs. If using 2% risk on each and all of them gets stopped out then we have lost 14% of the account in a few hours. Repeat this 2 more times with the same or different currency pairs and you get the ~40% DD in few days.

If we want to be sensible and really enable the 2% risk rule to protect our accounts, then we should not be allowing the EA to enter so many pairs of the same currency at the same time. This will fix the excessive DD problem. I think using 1% risk per trade we can open 2 trades with the same currency, or with 2% risk per trade only one. If there are several candidates with the same currency then some inbuilt logical criteria, or a direct manual choice offered to the user could decide which pair to enter.

Of course this aggressive trading can be just as profitable as detrimental, depending on the situation. If the EA enters all 7 JPY pairs and all of them goes into profit then we gains 7-fold profits as reward for the 7-times greater risk. I have run the EA only for one day and it gained 3.77% profits. This is the lucky side of the coin that balances the previously posted 40% DD.

I am seeing these errors though in Experts. Andy, are these errors insignificant?

2013.04.18 08:00:04 Multi_10_4_EAv2.01a GBPJPY,H4: object name passed to ObjectFind function cannot be an uninitialized or empty string

2013.04.18 08:00:04 Multi_10_4_EAv2.01a GBPJPY,H4: symbol name for MarketInfo function must be a string

Only ObjectFind calls are in my functions
drawGridBack() -> object name is hardcoded, can't be empty
LabelCreate() -> error should be intercepted
LabelSetText() -> error should be intercepted

Maybe my interception statement doesn't work properly:

Code: Select all

if ( labelName == "" )				// simplex2
	return;

Used to be a quick hack ...

Anybody else facing this error?

Do you run the EA OOTB? Any changes? How often does the error occur?

The MarketInfo stuff is non of my business ... at the moment ...

Hi,

I'm not interested changing anything to do with the entry strategy, after 5 weeks, we know the strategy works, only bad part is the drawdown, I'm reading up now how to simulate the trades within the EA, measure the drawdown then enter the trades when we have a drawdown.

Excellent post Yogi, you've described the cause of the excessive DD in a nutshell.

I imagine it might be quite difficult to implement what you're suggesting - and indeed if you choose to enter, say, 2 JPY trades instead of all of them then which ones do you go with & which do you leave out? Its getting into the realm of needing to use the CSS indicator.

Hi,

We have that built into the EA, just needs switching on:
extern bool useFilterCurrencyNumber = false;//Allow a currency, like JPY to trade NumberToTrade as below
extern int NumberToTrade = 2; <== number allowed to trade at the same time.

All right, quick hack of my quick hack:

Could you check the following and report whether the ObjectFind error still occurs:

Code: Select all

/* -----------------------------------------------------------
   create a label
   March 2013, simplex
   ----------------------------------------------------------- */
void LabelCreate(string labelName, int _corner, double x_coord, double y_coord) {
	//if ( labelName == "" )																							// simplex2
	//	return;
	if ( StringLen ( labelName ) == 0 )																							// simplex2
		return;
	if (ObjectFind(labelName) == -1) {
		ObjectCreate(labelName, OBJ_LABEL, 0, 0, 0);
	}
	ObjectSet(labelName, OBJPROP_CORNER, _corner);
	ObjectSet(labelName, OBJPROP_XDISTANCE, x_coord);
	ObjectSet(labelName, OBJPROP_YDISTANCE, y_coord);
}


/* -----------------------------------------------------------
   set text of a label
   March 2013, simplex
   ----------------------------------------------------------- */
void LabelSetText(string labelName, string text, int size, string font, color vcolor) {
	//if ( labelName == "" )																							// simplex2
	//	return;
	if ( StringLen ( labelName ) == 0 )																							// simplex2
		return;
	if (ObjectFind(labelName) > -1) {
		ObjectSetText ( labelName, text, size, font, vcolor );
	}
}

Just seek functions LabelCreate and LabelSetText, replace them with the new source (see above) and recompile.

Looking forward to your answer.

Great work Mr Long.

FxJoe and FridayStreet came up with a solution in Bunker's Big Mac and Fries EA. From what I recall there was a shadow basket that went active once a certain DD was reached.
